What type of feedback provides information about swing mechanics during the swing?

The correct choice is concurrent knowledge of performance (KP), which refers to feedback provided during the performance of a task. In the context of a golf swing, this type of feedback offers athletes real-time information about their swing mechanics as they execute the movement. This immediate feedback can be crucial for making necessary adjustments, enhancing skill acquisition, and improving performance.

Concurrent KP allows for a more dynamic learning environment as players can apply the feedback right away, reinforcing correct movements or addressing errors on the spot. By receiving this kind of feedback, athletes can better understand how their mechanics influence their performance, leading to faster and more effective learning and refinement of their skills.

This contrasts with other types of feedback such as terminal knowledge of performance, which is given after the completion of a task, delaying the opportunity for immediate correction. Delayed knowledge of results (KR) provides information about the outcome of the performance after it has been completed, which does not inform on the execution during the swing itself. Finally, prescriptive feedback focuses on suggestions for improvement rather than the mechanics happening in real-time. All these forms have their place in skill development, but for immediate feedback on swing mechanics during the swing, concurrent KP is essential.
